...PRELIMINARY DAMAGE SURVEY RESULTS FOR GORDON WI TORNADO...

Several supercell thunderstorms developed during the morning and
early afternoon hours of Thursday, July 18, 2019 starting around
11 AM near Moose Lake, MN. The first storm produced half-dollar
size hail near Foxboro, WI before dissipating. Another supercell
thunderstorm developed near Chaffey, WI and tracked east-
southeastward to a few miles northwest of Solon Springs, WI. The
storm then made a right turn and moved into the town of Gordon, WI
where it produced a tornado. The storm gradually weakened as it
moved across southern Bayfield County and dissipated near
Namekagon around 4 PM.

SURVEY SUMMARY:

The tornado began east of the intersection of Sand Road and Cabin
Lane. The NWS Duluth storm survey picked up the damage path where
it crossed Cabin Lane several hundred yards west of Sand Road.
Numerous uprooted and broken softwood trees were noted on either
side of Cabin Lane at that location. The damage at that location
was consistent with high-end EF-0 wind speeds of 75 to 85 mph. The
tornado continued east-southeast and  to EF-1
intensity south of the intersection of Sand Road and Cabin Lane.
Extensive tree damage was noted with nearly all trees in the area
broken or uprooted. This damage seemed consistent with winds of 85
to 95 mph. From that location to a point just west of Schaefer
Road a notch was cut through the trees which was approximately 80
yards wide and approximately one-half mile in length. All the trees
in this area were either broken or uprooted and the damage was
consistent with winds of 100 to 110 mph. The tornado weakened
quickly after crossing Schaefer road. A few broken branches and
uprooted trees were noted along Jackson Road and locations farther
east. It seems the tornado lifted between Schaefer Road and
Jackson Road, which is where we approximated the end of the track.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories.

EF0...Weak......65 to 85 mph
EF1...Weak......86 to 110 mph
EF2...Strong....111 to 135 mph
EF3...Strong....136 to 165 mph
EF4...Violent...166 To 200 mph
EF5...Violent...>200 mph
